Hello! I'm building a new Virtex4-FX60 device. I have built it with the new MPMC3 and a 256MB SO-DIMM. It works successfully with a "mem-test" type embedded program.
I cannot get it to boot a Linux kernel. I have traced it down to the MMU not getting mapped correctly. I can load the kernel via jtag, get the pre-boot messages on the serial but then when it tries to jump to 0xc0002218 (start_here: head_4xxx.S) it fails with a "Machine check exception; invalid instruction address". Using the debugger and examining the memory once the mmu is suppose to be configured, I see that it is not mapping 0xc0000000 to the proper location. I'm sure I've set something up wrong in my FPGA and I need to re-synthesize. But what? Any hints on which registers to look for or what I need to do??
